Patented Nov. 18, 1947 KNITTING MACHIN E to Phoenix Hosiery .Fohannes Paul Ludwig, Milwaukee, Wis, assignor Company,

Milwaukee, Wis,

a corporation of Wisconsin Application December 20, 1944, Serial No. 568,959

19 Claims.

This invention relates to straight knitting machines. More specifically it is concerned with knitting machines of the Cotton type ordinarily employed in the manufacture of full fashion hosiery.

The chief aim of my invention is to make it possible to economically produce on such machines integrally knitted stocking blanks of the kind disclosed in U. S. Patent No. 2,003,189, granted to Woldemar Heinitz on May 28, 1935, characterized by having cheek gussets of substantially square configuration wedgedly interposed between the ankle and foot portions and defined by gores or sutures which extend substantially at right angles to each other.

This desideratum is realized in practice, as hereinafter more fully set forth, through provision of an improved supplemental heel knitting means which is simple in construction and reliable in operation; which can be readily incorpo rated in existant straight knitting machines initially designed. for the producing of stocking leg blanks only, at relatively small cost without requiring any structural changes in the machines Or interfering with their normal mode of operation; and which includes mechanism for selecting auxiliary presser elements corresponding to needles of two end groups of heel needles first in gradually increasing numbers both inwardly and outwardly of the selvage edges of the blank and later in progressively decreasing numbers respectively to cause knitting by such needles of yarns taken from two different carriers in forming the heel cheeks, and for concurrently varying the traverse of the carriers correspondingly as required, while a central group of instep needles between the two groups of heel needles operates idly but retains its loops during the heel cheek knitting. k

Other objects and advantages will appear from the following detailed description of the attached drawings, wherein Fig. 1 is a fragmentary View partly in front elevation and partly in vertical section of a straight knitting machine conveniently embodying the present improvements.

Fig. 2 is a fragmentary view in front elevation of the left-hand end of the machine drawn to a larger scale.

Fig. 3 is a fragmentary view showing part of the machine in rear elevation.

Fig. 4 is a fragmentary plan view of the machine taken as indicated by the angled arrows IVIV in Fig. 3.

Figs. 5, 6, 7, 8 and 9 are cross sectional views 2 of the machine taken in different transverse planes.

Fig. 10 is a fragmentary sectional view taken as indicated by the angled arrows X-X in Fig. 2.

Fig. 11 is a fragmentary view in horizontal section taken as indicated by the angled arrows XIXI of Fig. 5.

Figs. 12, 13 and 14 are horizontal sectional views taken as indicated respectively by the angled arrows XII-XII, XIIIXIII and XIV-XIV in Figs. 6, 7 and 8.

Fig. 15 is a broken out View in vertical section taken as indicated by the angled arrows XVXV in Fig. 9.

Figs. 16 and 17 are fragmentary detail sectional views taken as indicated respectively by the,

angled arrows XVL-XVI and XVII-XVII in Fig. 15.

Fig. 18 is a fragmentary View in front elevation showing one of the unit devices for controlling knitting by one of the'two groups of needles used in forming the heel pockets of stockings in accordance with my invention, with the component parts of said unit in their normal or inactive positions.

Fig. 19 is a view corresponding to Fig. 18 showing the unit of Fig. 18 in operative condition.

Fig. 2D is a broken out view of the unit of Figs, 18 and 19 partly in rear elevation and partly in section.

Fig. 21 is a fragmentary cross sectional view taken as indicated by the angled arrows XXI- XXI in Fig. 18.

Fig. 22 is a cross sectional view taken as indicated by the angled arrows XXIIXXII in Fig. 19.

Fig. 23 is a fragmentary detail view taken as indicated by the angled arrows XXIIL-XXIII in Fig. 18.

Fig. 25 is a fragmentary View of a control means as it app-ears when viewed from the front or the side opposite to that from which Fig, 24 is observed but with the means in operative position.

Fig. 26 is a fragmentary view corresponding to Fig. 24 with the parts differently positioned.

Fig. 27 is a fragmentary sectional View taken as indicated by the angled arrows XXV'lI-XXVII in Fig. 24.

Fig. 28 is a detail view in perspective of one of the elements of the control means.
